After updating to 10.10.3 my Mac Mini 2014 is having Problem with WIFI, its connecting but after a couple of minutes the Internet Connection goes off!! Have to disconnect WIFI and switch on again and it works again for a couple of minutes!!
Anybody elase having the same Problem??
Mac mini, OS X Yosemite (10.10.3), 2014
I have the same!
MacBook Pro 13" (mid 2012)
Restart your WiFi Router (such as, Airport Extreme) and then, restart all your devices that are using your WiFi network.
I have a mac mini 2014 too. Just updated to 10.10.3 and have the same problem. Works for 5 mins and then by by. Try if you are using a magic mouse to turn it off and see if that helps. That is what I am testing now.
My wifi network is useless after updating to OSX 10.10.3. Evidently, the update corrupted the wireless network itself since my mobile devices are unable to access the network also. I recreated my wifi network from scratch but this failed to resolve the problem. Even when I connected to my Apple router via Ethernet, I was unable to connect to the Internet. Ultimately, I had to connect directly to my ISP's provided modem/router via Ethernet to access the Internet.
Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Be sure to test on more than one Wi-Fi network, if at all possible. A desktop computer can be tested with a mobile hotspot, such as the hotspot created by a cell phone. If the problem only exists on one network, then the access point of that network should be the focus of your attention, not the computer.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local only
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first. Turn Wi-Fi off and then back on. You'll be prompted for the password when you reconnect. Save it in the keychain.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
I had the same issue,
what ended up working for me was to trash the /library/preferences/system configuration folder and restart.
It is very important if you do this to make sure you DO NOT pull this folder from system/library.
I have the same problem here! New Mac Mini, bought 2 weeks ago. After a few minutes connected over WIFI, the wifi connection drop me off. Need to reconnect and the game starts new. WIFI is after the latest Yosemite update useless. This also happen now when i´m in a 5Ghz network.
My old Mavericks MacBook dont have any problems.
This an ongoing problem. Honestly Apple need to get it together or replace the wireless cards. I travel often and am dependent on my Mac for work, but honestly getting frustrated. I tried the above steps and nothing helped.
looks like the Problem is gone, rebooted the Router and removed all connection and reconnected, now it seem to work 🙂 Fingers crossed...
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
Or you can use your Apple ID to register with this site and go the Apple BugReporter. Supposedly you will get an answer if you submit feedback.
Have you guys tried this:
Backup and then delete the contents of /Library/Preferences/SystemConfiguration/
Reboot and check if your issues exist. You might have to re-create a New Network Location from under System prefs->Network on reboot.
You nailed it brother! I didn't delete the entire SystemConfiguration folder however. I only deleted the .plist(s) that had Airport in their name. I rebooted my Mac and reset my router to its factory default settings. Then I recreated my wifi network. For extra insurance, I named the new network differently. It restored my wifi connectivity to all my devices after I logged into the new wifi network on each device. THANK YOU
This helped me (at least for now):
same issue here, i have a macbook air mid-2013, plus since the update "messages" and "facetime" takes extremely long time to load for this reason voiceover is almost useless.
Same issue here on 2013 macbook air 13", 10.10.3. Had wifi issue since 10.10.1. Definitely a software issue. I installed windows via bootcamp and Wifi is working perfectly fine. Guess i have to stick with windows on my macbook air for a little longer. Hope Apple is taking this issue seriously, no fix after 2 updates?!
